  • Publication number: 20230181360
    Abstract: Embodiments of the invention provide hydrodissection and/or PCO prevention or reduction in a patient undergoing eye surgery. In one embodiment, the invention is a surgical device for cutting and excising a portion of tissue, for example in performing a lens capsulotomy. A capsulotomy tip is inserted into an eye through an incision in the surface of the eye. The capsulotomy tip includes a suction cup to provide suction to the lens capsule. Then suction is applied via the suction cup to secure the capsulotomy tip to the eye. In some embodiments, after the capsulotomy tip is secured to the lens capsule, a cutting element of the capsulotomy tip is used to cut a tissue of the eye. Fluid is pushed through the capsulotomy tip and the capsulotomy tip is removed from the eye. Moreover, disclosed is an intraocular lens (IOL) to be used in conjunction with the surgical device.

  • Patent number: 9814515
    Abstract: A laparoscopic instrument assembly with a handle member and a removable tip. The handle member and removable tip are mated using a double threaded design which provides a secure connection with low electrical resistance. Electrical energy is provided through an inner shaft to the removable tip, and a return energy path is formed using an outer tubing of the instrument assembly. The removal tip includes a cutting and sealing device with a resistive member that is provided with the electrical energy, thereby enabling the tip to cut and seal tissue.

  • Patent number: 5676784
    Abstract: A heater (12) for a catheter (10) used in monitoring constant cardiac output is fabricated using a bifilar wire (21) coated with polyvinyl chloride (PVC) like the material used for the catheter. The bifilar wire is coated with the PVC using a conventional extrusion technique, producing a coated lead (24, 32). This coated lead is wrapped around the exterior surface of the catheter, forming a helical coil. Heat is applied to the coated lead to melt the PVC coating, causing it to bond the lead to the catheter. The melted PVC also flows into gaps (23) or notches between adjacent coils of the lead, producing a relatively smooth outer surface for the heater coil when the PVC coating cools. The bifilar wire can alternatively be wrapped in-line with PVC tape (29) or film and the PVC material heated to flow around the wire, bonding it to the catheter's outer surface.
